I have made a tcp ip program but I am able to connect from my laptop to my office computer. ie laptop runs server and office runs client but I am not able to connect wise versa. I showed the demo but it does not work for any one else as we need server at office. please any one can respond...

I knew how these work; I stumbled upon this by accident. I'd like to say though, kudos on the CLEAREST explanation I've EVER seen on this topic. You really managed to break it down just right for people.

Keep it up!

I have a problem with my email system,, probably stmming from spam spewing from my "internet server". The 1.2.3.4 is what has been blocked by spamcop. But I have a "static" IP assigned by the ISP (or I thought). I therefore cant send out emails, they just bounce.
I connect to the net through a telephone line, using ADSL US Robotics Modem. Though it is said to be secure, I haven't heard tme to explore how I would avoid such problems with it. The machine has been running Kaspersky internet security, and am now trying AVG Internet Security, but all havent yet managed to stop the problem of almost 2 months now.
How may I sort my self out once and fo all?

I would like to use netmeeting to "ring" my home PC being behind NAT router. Normally, I would use an IP to do that. However in this case, it won't for obvious reasons. Is there a way how to solve this?

hi i have similar problem as stated above..i want to stream my media over internet using windows media encoder and the url address to connect to my stream is http://10.1.1.12:8080 where 10.1.1.12 is static ip from LAN and 8080 is port i am using for straming..i already opened this port in my router .but i am confused with my url address as someone on other end cann't access my stream with this url.and i tried to the dynamic ip given to me by my isp(http//:203.X.X.X:8080) and its not working aswell..my question is how can someone on other end can access my computer and what url they need for it?

Yes. It sounds like your machine isn't behind your router at all. Check the topology in this article: http://ask-leo.com/how_should_i_set_up_my_home_network.html

Could anyone help me with a problem i have. I have the same physcial network topology as the one shown in the tutorial above but the problem is that my pc is receiving the same ip address as the router-ie its not getting a lan ip address.Does this mean that my pc is not 'sitting' behind my router and that my pc could be exposed?

Zane: this requires that you know what ports you need to use, and then configure the router to forward those ports to the specific computer you want to access. You would use your IP address as it appears on the internet.

Your linksys probably needs to be configured to use the static IP address - I suspect it's still using DHCP to get an IP, even though it may not need to. Check with Direcway for the specifics - I'm not exactly sure how they manage that kind of thing.

I have a question for you we recently called direcway to ask then to set me up with a static ip address. So they did we did what they said but if I go to whatismyipaddress.com it still keeps changing. But I need to be the same because I need have it stay the same because I bring work home . That was the main reason for asking my ISP to add a static ip address. What should I do. Is there something that I forgot I have to configure. Right know I am running XP on my computer. My ISP is connected to a Linksys and the Linksys is connected to my computer. Please try to help me figure out what I need to do.

Ivan,

It was a joke. :-)

But in case someone had found some script kiddie nonsense on a newsgroup or hAx0R site, thought they'd do some evil with it, but didn't even know what the IP address for localhost was... I figured I'd leave off the smiley and let them attack themselves.

No Greg, as far as I know 127.0.0.1 address simply means "local computer", while additionally 0.0.0.0 means "any computer".

And if you ever want to try any nasty hacking, exploits, or denial of service attacks, aim them at 127.0.0.1. That's Microsoft's main IP address.
